Active clinical trials for "Mesothelioma"

Pemetrexed is a multi-folate inhibitor approved in the treatment of non-small cell lung cancer (NSCLC) and pleural mesothelioma. Its toxicity profile is mainly hematologic (anemia, neutropenia and thrombopenia) and can be limiting when > grade 2 according to NCI-CTCAE criteria. First clinical trials highlighted hematologic toxicity, especially anemia, which was reduced by decreasing pemetrexed dosage from 600 to 500 mg/m² Q3W and by adding systematic vitamin supplementation (B9/B12). Despite this, incidence of hematological toxicity remains frequent with anemia occurring in more than 20% of patients treated by pemetrexed in combination. Methotrexate, a well-known antineoplastic drugs used in several cancer and non-cancer disease conditions can also induced severe hematologic toxicity in case of methotrexate-reduced elimination and, as a consequence, its accumulation. For example, the elimination of methotrexate is mediated by tubular secretion through type 1 and type 3 organic anion transport (hOAT1 and hOAT3). Association with drugs that inhibits hOATs can induced a hematological toxicity caused by methotrexate accumulation. Among these, proton pump inhibitors (PPIs) are known to inhibit hOATs. The drug interaction that results from their combination with methotrexate is clinically relevant and lead to an increased hematological toxicity. However, hypothetical drug interaction between PPIs and pemetrexed is unknown while pemetrexed seems to be mostly eliminated by hOAT3 (11-fold higher than methotrexate). One study revealed lansoprazole to inhibits in vitro hOAT3. This same study investigates in a retrospective chart patients treated by pemetrexed and the study found a significant association between combination with PPI and hematological toxicity by pemetrexed. Unfortunately this study lacks of relevant methodology and suffered from its retrospective chart. This potential drug interaction must be a real concern for oncologists and clinical pharmacists. The investigators aim to investigate the potential association between PPIs and pemetrexed combination and the incidence of hematological toxicity in a multicenter and prospective study.

The goal of this protocol is to determine the prevalence of somatic and germline mutations in BAP1 (BRCA associated protein-1) among patients with mesothelioma , choroidal nevus, primary uveal melanoma (UM), or metastatic UM seen at our institution.

This study is to evaluate the effects (good and bad) of ALIMTA and Cisplatin or ALIMTA alone on you and your malignant pleural mesothelioma as well as make ALIMTA available to patients who qualify for treatment.

SPECTAlung is a program aiming at screening patients with thoracic tumors to identify the molecular characteristics of their disease. The thoracic tumors include lung cancer, malignant pleural mesothelioma, thymoma or thymic carcinoma at any stage. Once the molecular characteristics are identified, there might be the possibility to offer these patients access to targeted clinical trials.

Prospective exploratory study specifically investigating the role of 11C-Methionine PET/CT imaging in patients affected by Malignant Pleural Mesothelioma (MPM) and candidate to pleurodesis.

This laboratory study is collecting tumor tissue and blood samples from patients with gynecologic tumors. Collecting and storing samples of tumor tissue and blood from patients with cancer to study in the laboratory may help in the study of cancer.

To date, the different biopsy methods, such as CT-guided pleural biopsy, mediastinal biopsy, endosonography and thoracoscopy have their limitations in diagnosing pleural malignancies, such as mesothelioma. Sampling errors frequently occur resulting in the common histological finding of 'non-specific pleuritic/fibrosis', which presents a great uncertainty for clinicians and patients. Confocal laser endomicroscopy (CLE) provides real-time imaging on a cellular level, however data of CLE in pleural malignancies are lacking.

Multicentric, international, web-based prospective documentation of the indications and results of Pressurized Aerosol Chemotherapy (so-called PIPAC or PITAC) for treating malignant pleural and peritoneal diseases. Indication is decided by the treating physician. There are no predefined inclusion or exclusion criteria.

This is a prospective study evaluating the effect of expression of CD74 and VEGF on outcome of treatment in patients with malignant pleural mesothelioma receiving Pemetrexed/Platinum protocol. The paraffin blocks of the patients will be tested for CD74 and VEGF before starting treatment using IHC and the results will be correlated with the outcome of treatment during evaluation.

RATIONALE: Studying levels of mesothelin and osteopontin in samples of blood from patients with mesothelioma or atypical mesothelial hyperplasia may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at mesothelin and osteopontin as diagnostic markers in patients with mesothelioma or atypical hyperplasia.
